TissuesCells are arranged in ____________________________

that provide specific functions for the bodyCells of different tissues are

_________________________________ differently, which leads to their differences in _____________________________.

The Tissues of the body include four major types: Epithelial ______________________________________ Muscular Nervous

Epithelial TissuesWidespread throughout the body – Covers

________________________________ and lines body surfacesAnchored to a ____________________________ membraneMade up of tightly packed cells containing little

intercellular materialGenerally lack ______________________________________Are frequently replacedFunction in protection, secretion, absorption,

excretion and sensory reception.There are 9 types of Epithelial Tissues

Structure of Epithelial Tissues

Page 5: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Simple Squamous Epithelium

Made up of a ____________________ layer of thin, flattened cells

Functions in the exchange of

___________________ in the lungsLines blood and

lymph vessels as well as body cavities

Page 6: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Simple Cuboidal Epithelium

Consists of a single layer of ___________________-shaped cells with centrally located nuclei

Functions in ____________________ and absorption in the kidneys and in secretion in glands

Page 7: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Simple Columnar Epithelium

Made up of rows of

_________________________ cells whose nuclei are all located near the basement membraneLines the ______________,

stomach and intestines where it protects underlying tissues, secretes digestive fluids and absorbs nutrients

In the intestine, these cells possess _____________________ that increase the surface area available for absorption.

Page 8: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Pseudostratified Columnar Epithelium

Appeared ______________________ due to the varying positions of their nuclei within the rows of cells, but are not truly layered.

________________ may be present

Cilia on these cells aid in moving eggs through oviducts to the uterus in the female reproductive system

Page 9: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Stratified Squamous Epithelium

Made up of _______________

of ___________________ cells that are designed to protect underlying layersMakes up the outer

layer of skinLines the

________________, throat, vagina and anal canal

Page 10: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Stratified Cuboidal Epithelium

Consists of two to three layers of ___________________________

cells lining a _________________ (opening) of the mammary glands, sweat glands and pancreas.Several layers of cells

provide greater protection than a single layer.

Page 11: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Stratified Columnar Epithelium

Consists of several layers of cells

Found in part of the male

_______________ and parts of the pharynx

Page 12: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Transitional EpitheliumDesigned to _________________________ and return to its

normal sizeFound in the urinary bladder

Design provides distensibility (_________________________) and keeps urine from diffusing back into the internal cavity

Page 13: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Glandular EpitheliumMade up of cells designed to produce and secrete

substances into _________________________ or into body fluids___________________________ glands – glands that

secrete products into ducts___________________________ glands – glands that

secrete products directly into body fluids and blood.

Glandular Epithelium

Page 15: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Connective Tissues

Bind, support, protect, serve as __________________________________, fill spaces, store fat, produce blood cells, protect against infection and repair tissue damage

Unlike epithelial tissues, connective tissues have abundant _________________________________ material and have good blood supplies (except in cartilage)

There are 6 types of connective tissues

Page 16: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Loose Connective Tissue

Forms delicate, thin ___________________________ throughout the body that bind body parts together.

Binds the skin to underlying __________________________ and fills spaces within muscle.

Page 17: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Adipose Tissue

Designed to store ________________

Found beneath the skin, around joints, padding the

_________________________ and other internal organs, and in certain abdominal membranes.

Page 18: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

Dense Connective Tissue

Consists of densely packed ____________________ and is very strong, but lacks a good blood supply.

Is found as part of

___________________ and ligaments

Page 19: Chapter 5 Tissues. Tissues Cells are arranged in ____________________________ that provide specific functions for the body Cells of different tissues

CartilageProvides a supportive framework for various

structures._______________________________ Cartilage – is white with

abundant fine collagen fibersIs found at the end of bones and supports respiratory

passages

__________________________________ Cartilage Provides a framework for the external ears and parts of

the larynx

_____________________________________________Tough tissue that provides a shock-absorbing function

in intervertebral disks and in the knees and pelvic girdle
